Spare battery: remove empty battery, switch battery, you are back to 100% Powerbank: mess with cables, keep phone plugged until it's charged and wait

If there is a market for spare batteries, there might be a market for external battery chargers as well > swap battery in the morning instead of charging, place empty battery on charger, repeat the next day

Spare batteries are a nightmare to handle. Far too easy to bend or have something short-circuit the pads, and you have to shut down and restart your phone.

However, what is needed desperately is the ability to quickly change a degraded battery.

		Spare batteries that are designed as internal batteries not to be easily swappable, yes. Look at DSLR cameras: take out in 1 second, put in in 1 second, physically robust. We absolutely can have the best of both worlds. We just need to align the smartphone manufacturers to user serviceability and right to repair… even if they go kicking and screaming since they decided their bottom line is most important.
